Answers

Answer:

y = 15

Step-by-step explanation:

y - 58 = -43

add 58 to both sides

y = 15

Answer:

y = 15

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

y - 58 = -43

Step 2: Solve for y

Add 58 on both sides:                    y = 15

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Substitute in y:                   15 - 58 = -43Subtract:                             -43 = -43

Here we see that -43 does indeed equal -43.

∴ y = 15 is the solution to the equation.

2) In A ABC , if LA = 60° , LB = 450 then find tc.​

Answers

Given:

In ∆ABC,

Angle A = 60°

Angle B = 45°

To Find:

The measurement of Angle C.

We know that the sum of all the interior angles of a triangle is 180°.

Explanation:

Angle A + Angle B + Angle C = 180°

By putting the respected values, we get

60° + 45° + Angle C = 180°

or, 105° + Angle C = 180°

By transposition method, we get

Angle C = 180° - 105°

Angle C = 75°

Answer:

The measurement of Angle C is 75°

Evaluate the expression for y= -1 -13y-16

Answers

Answer: y = -17/14

Step-by-step explanation:

y = -1 -13y - 16

First we must isolate the variable:

y+13y = -1 - 16

Next we must add like terms:

14y = -17

Finally, divide 14 on both sides:

14y/14= -17/14

Answer: y = -17/14

Solve for x. Round your answer to the nearest tenth.

Answers

Answer:

The Pythagorean theorem should help you out. Since you already know two sides of the triangle, you can do a^2 + b^2 = c^2

So in this problem, 16.5^2 + 9.2^2 =
272.25 + 84.64 = 356.89

Pasty you would take the square root of 356.89 and you would get x = 18.89 or 18.9 rounded to the nearest tenth

You can check your work by the Pythagorean theorem once more. 16.5^2 + 9.2^2 = 18.9^2 and you should get the same approximate answer (it will be a little bigger because you rounded)
